Ok, thanks. Here's the relevant part of the log: 2月 26 21:34:29 athena systemd-udevd[499]: eth0: Failed to rename network interface 2 from 'eth0' to 'enp0s31f6': Device or resource busy 2月 26 21:34:29 athena systemd-udevd[499]: eth0: Failed to process device, ignoring: Device or resource busy So, systemd-udevd does attempt to rename the interface but something is trying to use the network interface before it has been renamed, which is why the rename fails. Now you need to find out what part of the system is using eth0 early in the boot process.
